Have to go with Buck on this one. I watched the video posted to the Guardian article half a dozen times, trying to discern any context to what the video shows. Full disclosure, I, as many lizards know, am extremely skeptical and critical of the “reporting” that the Guardian and other media outlets do when it comes to all things Israel, so, although I tried to view the video objectively, I have to admit that I am suspicous of the way Guardian reported the story and the spin they try to place on the incident.

With that said, here’s my two cents. Everything about the clip suggests that something happened before the start of the clip, and that this kid was not exactly chosen at random for abuse. The body language of the second officer, the one who apparently delivers the kick, also suggests that his action was in response to some previous action by the kid which took place before the beginning of the clip.
Now, what that act was, or whether it in any way justified the response, clearly cannot be discerned from the video. But if past experience is a guide, the Israeli authorities will investigate and, if the officer’s actions were improper, appropriate action will be taken against him. If, on the other hand, the kid had just committed an act of violence againt the officer — i.e., threw stones, a brick or some other projectile that the Guardian and its ilk do not consider to be violent acts when directed against Israelis — then what I viewed in the clip shown by the Guardian takes on a whole different meaning.
